I seem to be having the same difficulties here on Natty.
/etc/security/limits.d/audio.conf is correctly set up.
ulimits -l -r tells me I have unlimited memory and max priority of 95
I am definately a member of the Audio group.

Firewire is working correctly (will start without realtime, alsa backend
fails to get realtime also) and yet starting jackd will yeild the following.

jackd -d firewire

Something else seems to be going wrong here.

Have you tried modifying /etc/udev/rules.d/something (debian/ubuntu) or
/etc/security/console.perms.d/60-raw1394.perms (fedora)? =A0Make sure you
assign your security group (audio?) to the /dev/raw1394 device.
